Barcode and QR Code Reader OpenCV Python With Source Code

The Barcode and QR Code Reader OpenCV Python was developed using Python OpenCV. In this post, I will show you how to build a Barcode and QR Code reader using Python. This is a great machine learning project to get started with computer vision.

A Barcode Reader OpenCV Python are very cool and interesting because they store information in a different format. The fun part about them is we can’t really tell what they are storing until we scan them. It’s like playing a puzzle game. And one more thing that I like about them is they can be part of the physical world and still connects us to the internet world.

In this Python OpenCV Project also includes a downloadable Python Project With Source Code for free, just find the downloadable source code below and click to start downloading.

What is OpenCV?

OpenCV (Open Source Computer Vision Library) is an open-source computer vision and machine learning software library. OpenCV was built to provide a common infrastructure for computer vision applications and to accelerate the use of machine perception in commercial products.

barcodes = pyzbar.decode(image)
for barcode in barcodes:
    (x, y, w, h) = barcode.rect
    cv2.rectangle(image, (x, y), (x + w, y + h), (255, 0, 0), 2)

    barcodeData = barcode.data.decode('utf-8')
    barcodeType = barcode.type
    text = "{} ( {} )".format(barcodeData, barcodeType)
    cv2.putText(image, text, (x, y - 10), cv2.FONT_HERSHEY_COMPLEX, 0.5, (255, 0, 0), 2)

    print("Information : \n Found Type : {} Barcode : {}".format(barcodeType, barcodeData))

cv2.imshow("Image", image)
cv2.waitKey(0)

Summary

I think Barcodes/QR codes are very cool and interesting because they store information in a different format. The fun part about them is we can’t really tell what they are storing until we scan them. It’s like playing a puzzle game. And one more thing that I like about them is they can be part of the physical world and still connects us to the internet world.
